Single-Phase Variable Output
Static Voltage & Frequency Converters

The Ashley-Edison (UK) FCL-range of Single-Phase Variable Output Static Voltage and Frequency Converters / Changers are primarily intended for applications where there is a need to replicate the various nominal utility mains voltages and civil frequencies deployed throughout the world. This makes them ideal for use in testing centres, research laboratories, and testing on production lines.

In addition, FCL Frequency Converters keep the load equipment running through utility voltage fluctuations and frequency variations, delivering a stable and clean voltage and frequency supply to the load equipment.

Supplied in IP20 style enclosures for indoor use, models are available in 14 different power ratings from 1 to 150 kVA.  Where requested, they can be provided housed in IP54 / NEMA 3 Style enclosures suitable for outdoor, or more challenging internal environments

Suitable for all load kinds, including Resistive, Inductive, and Capacitive types (see advisory note) models are available for situations where the incoming mains utility supply is either 220 to 240V (H Models), 100 to 127V (L Models), and 256 to 347V (HX Models).

 As is often required for Aviation and Military applications, on special request, models are also available configured to deliver up to a 400 Hertz output.

How do you ensure the correct sizing of a Static Frequency Converter?

Our FCL Series of Static Voltage and Frequency Converters have both maximum kVA (Apparent Power) ratings and kW (Real Power) ratings – the difference between the two being commonly referred to as the Power Factor.

In general, when sizing the Frequency Converter neither the kW nor kVA rating of a Frequency Converter should be exceeded.

Equipment nameplate ratings are often stated in kVA, which makes it difficult to know the kilo-watt ratings. If using equipment nameplate ratings for sizing, a user might configure a system, which appears to be correctly sized based on kVA ratings, but actually exceeds the Frequency Converters kW rating. By sizing the kVA rating of a load to be no greater than 60% of the kVA rating of the Converter, it minimizes the risk of exceeding the Watt rating of the Converter. Therefore, unless you have a high certainty of the Watt ratings of the loads, the safest approach, and widely considered to be the ‘best practice’, is to keep the sum of the load nameplate ratings below 60% of the converters kVA rating.

Where the load type is inductive in nature such as motors (fans, pumps, etc), solenoids, and relays it is essential that high inrush current and short-time overload factors are fully considered. With motors (without a soft start facility) typically drawing on start-up current 5 to 7 times the stated rating of the motor it is recommended that a Frequency Converter is selected that is 3 times the stated rated capacity of the load.
